boinc does not recognize valid CUDA GPU, nvidia GT 710

[Peter D.]

According to <http://www.geforce.com/hardware/desktop-gpus/geforce-gt-710/features> my GPU supports CUDA, but the log from BOINC says that no GPU was found.

It used to work for me when I had an nVidia GT 610.

nVidia's web pages are a little inconstant, and the GT 710 appears to have been left of the list in at least one place, despite lesser cards like the GT 705 and the older GT 610 being listed.

I would say:
Update to Ubuntu 16.04
Update to boinc 7.6.x
Update your CUDA driver.

On 14.04, the cuda detection was far from ideal, and the driver seems to be not supporting it anyway, so I would wild guess that before blaming boinc, it needs to be updated.
(BTW Ubuntu 16.04 has a nice boinc-client-nvidia-cuda package that installs the driver for you)
